It's 47 above here, but the wind is 20-30 MPH. Since it's a bit windy for flying, I decided to get some static RPM data on the 5030 & 5043 props with my Hyp 2s packs. The testing was done with Beast #2, so I re-tested the stock prop to establish a baseline.
910' AMSL, 70 F, 30 sec into the run on a freshly-charged pack. The GWSProps spreadsheet was used to calculate thrust:
*May not be accurate, as the stock prop's t-constant may or may not be similar to the GWS prop.
**Calculated pitch-speed. Prop slippage and in-flight unloading not taken into account.
I found it interesting that in my tests, the 5030 spun faster than the stock prop. Seems like an anomaly, but I did get the same result with two packs. I'm not sure what to think about that. Going by the data, the 5030 should provide longer flight-times, a bit more top-speed, and slightly better vertical than the stock prop. Also, the data suggests that the 5043 should not...Continue Reading

I'm a middle-aged, techie-type of guy who refuses to 'get old'. I grew up in an aviation family. I spent hundreds of hours flying with my dad, who eventually retired with 33,500 hours. I was 9 when he taught me to fly. I've been flying RC since 1984.
